Systems and methods for detection of potential health issues

ABSTRACT

A device for detecting potential health issues includes a retinal scanner configured to capture retinal data of the user, a blood pressure sensor configured to capture blood pressure data of the user, an alert module configured to alert the user of a potential health risk, and at least one processor communicatively coupled to the retinal scanner, the blood pressure sensor, and the alert module.

TECHNICAL FIELD

This disclosure generally relates to detection of potential health issues, such as chronic kidney disease.

BACKGROUND

Kidneys typically function to filter wastes and excess fluids from a person's blood, which are then excreted in a person's urine. When a person's kidneys lose their filtering capabilities, dangerous levels of fluid, electrolytes, and wastes can build up in the person's body. Chronic kidney disease (CKD) is a condition characterized by gradual loss of kidney function over time. CKD includes conditions that damage kidneys and decrease their ability to keep a person healthy. As CKD advances, wastes can build to high levels in blood and make the affected person feel sick. Affected persons may also develop complications like high blood pressure, anemia (low blood count), weak bones, poor nutritional health, and nerve damage. Also, kidney disease increases the risk of having heart and blood vessel disease. These problems may happen slowly over a long period of time. CKD may be caused by diabetes, high blood pressure, and other disorders. When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life.

CKD is typically classified using five severity based stages. End stage renal disease (ESRD) is the last stage (stage five) of CKD. At this stage, kidneys are only functioning at 10 to 15 percent of their normal capacity. When CKD develops into ESRD, dialysis or a kidney transplant is necessary to stay alive. In many instances, detection and treatment can keep CKD from getting worse.

DETAILED DESCRIPTION

It is common to not experience symptoms of CKD in the early stages of CKD development. Because of this, CKD may not be detected until it has advanced to stage 5 (i.e., ESRD) in many instances. For example, some studies estimate that less than 40% of people that have stage 4 CKD are aware of their condition. Furthermore, the awareness rate decreases for people with earlier stage CKD (e.g., some studies estimate that the awareness rate for stage 2 CKD is less than 20%). As a result, CKD is typically not detected and treated until it advances to ESRD, which can typically require dialysis or kidney transplants. Therefore, systems and methods that can facilitate early diagnosis to the public on a large scale can be desired.

The present disclosure provides systems and methods for detecting potential health issues, such as CKD. The systems and methods can be implemented with public kiosk technology. For example, the systems and methods can be used utilized in a public setting such as, an airport or supermarket, to help address public health issues at a large scale. In general, the systems and methods described herein can act as an initial screening for potential health issues, and make recommendations to visit a healthcare provider (HCP) if it is determined that a user has a potential health issue.

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. It will be apparent, however, that the present disclosure may be practiced without these specific details.

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, circuits, and networks have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.

Several features are described hereafter that can each be used independently of one another or with any combination of other features. However, any individual feature may not provide any of the advantages discussed above or may provide one of the advantages discussed above. Although headings are provided, data related to a particular heading, but not found in the section having that heading, may also be found elsewhere in this description.

FIG. 1 shows an environment 100 including a system 101 for generating an anonymized acoustic fingerprint for the environment 100. As shown, the environment 100 is an airport terminal. However, the environment 100 can be any public or private setting, such as a supermarket, hospital waiting area, school auditorium, and so forth. The environment 100 includes a user 150 receiving treatment from a system 101 for detecting potential health issues. For illustrative purposes, the system 101 is described as detecting whether the user 150 is at risk of having or developing CKD. However, in some implementations, the system 101 can detect whether the user 150 is at risk of having or developing other health issues, such as diabetes, chronic heart disease, and so forth.

The system 101 includes a retinal scanner 102, a blood pressure sensor 103, a user interface 104, a weight sensor 105, a urinalysis sensor 106, an alert module 107, and one or more computer processors 110. The one or more computer processors 110 are communicatively coupled with the retinal scanner 102, blood pressure sensor 103, user interface 104, weight sensor 105, urinalysis sensor 106, and alert module 107. As discussed in more detail later with reference to FIG. 2, at least one of the retinal scanner 102, blood pressure sensor 103, user interface 104, weight sensor 105, or urinalysis sensor 106 can capture health data of the user 150, and transmit the health data to the one or more computer processors 110. Furthermore, as discussed in more detail later with reference to FIG. 2, the computer processors 110 can use the health data to determine if the user 150 is at risk of having CKD and cause the alert module 107 to alert the user 150 that the user 150 may be at risk of having or developing CKD. In some implementations, the system 101 can recommend that the user 150 visit a HCP. In some implementations, the system 101 can inquire as to whether the user 150 has a primary HCP, and, if the user 150 does not have a primary HCP, the system 101 can recommend to the user a primary HCP with the necessary qualifications for treating the detected potential health issues (i.e., CKD).

FIG. 2 shows the system 101 for detecting potential health issues, in accordance with one or more embodiments of the present disclosure. As indicated earlier, the system 101 includes a retinal scanner 102, a blood pressure sensor 103, a user interface 104, a weight sensor 105, a urinalysis sensor 106, an alert module 107, and one or more computer processors 110. In some implementations, the system 101 includes a bio-impedance sensor 108.

The retinal scanner 102 is configured to capture retinal data of a user. For example, the retinal scanner 102 can cast a beam of low-energy infrared light into the eye of the user as the user's eye is positioned in front of and in close proximity to the retinal scanner 102. The beam of infrared light can trace a standardized path on the retina of the user to capture a retinal image. In some implementations, the retinal scanner 102 compile unique features of the network of retinal blood vessels into a retinal template. For example, because retinal blood vessels are more absorbent of infrared light than the rest of the eye, which causes the amount of reflection to vary during the retinal scan, the retinal scanner 102 can encode this pattern of variations as a retinal template. In some implementations, the retinal scanner 102 is configured to perform optical coherence tomography (OCT), which can involve using light waves to capture high-resolution cross-section images of the retina. In some implementations, the retinal scanner 102 includes a a fundus camera, which refers to retinal imager that includes a specialized low power microscope with an attached camera designed to photograph the interior surface of the eye, including the retina, retinal vasculature, optic disc, macula, and posterior pole (i.e. the fundus).

The blood pressure sensor 103 is configured to capture blood pressure data of a user. In some implementations, the blood pressure sensor 103 is an electronic sphygmomanometer. A sphygmomanometer refers to a device that includes an inflatable cuff, in which a user typically places their arm, to collapse and then release the artery under the cuff in a controlled manner to measure systolic and diastolic blood pressure by oscillometric detection. Although shown as a sphygomanometer, in some implementations, the blood pressure sensor 103 is an optical sensor against which a user can press their finger (or forehead). For example, the blood pressure sensor 103 can utilize Photoplethysmography (PPG) to measure oxygen saturation, blood pressure, cardiac output and so forth. In some implementations, the optical sensor measures how light penetrating through the finger changes its characteristics and determine, based on these changing characteristics, a measurement of the user's blood pressure. In some implementations, the blood pressure sensor 103 is configured to measure oxygen saturation in the blood by using a pulse oximetry device that measures light absorption of hemoglobin. In some implementations, the blood pressure sensor 103 measures, using PPG, cardiac output, which refers to the product of the heart rate (or number of heart beats per minute) and the stroke volume (volume of blood pumped from the ventricle per beat). In some implementations, the blood pressure sensor 103 measures, using PPG, vascular resistance, which refers to the resistance that must be overcome to push blood through the circulatory system and create flow.

The user interface 104 includes a display device, such as an electronic display device. The display device can be configured to act as a touchscreen display device. In some implementations, the user interface 104 is a graphical user interface (GUI). The user interface 104 is configured to allow a user of the system 101 to interact with the system 101 through graphical icons and visual indicators. For example, the user interface 104 can use windows, icons, menus, pointer paradigm (WIMP) to allow a user to interact with the system 101. In some implementations, the user interface 104 cooperates with the display device to provide a user with a touchscreen GUI. Additionally, or alternatively, the user interface can include one or more input devices such as a mouse and/or keyboard communicatively coupled with the system 101. The user interface 104 can also use a post-WIMP paradigm typically found in touchscreen-based GUIs. In some implementations, the user interface 104 is configured to display images in the form of still photographs and/or videos.

The user interface 104 is configured to capture lifestyle data of a user of the system 101. Lifestyle data can represent voluntary choices of a user, such as alcohol usage and tobaccor usage. Additionally, or alternatively, lifestyle data can represent biological or inherited features of a user, such as race, ethnicity, height, and family medical history. For example, the user interface 104 can present a set of questions to a user. The questions can be helpful in determining if the user has is at risk of having or developing a health issue, such as CKD. For example, the user interface 104 can prompt a user to answer questions related to the user's age, height, race, ethnicity, tobacco usage, family history of kidney disease, alcohol usage, diabetic history, and so forth. The user interface 104 can also prompt a user to answer questions related to whether the user has been experiencing nausea, vomiting, loss of appetite, fatigue, sleep problems, changes in urination frequency, decreased mental sharpness, muscle cramps, persistent itching, chest pain, swelling of feed or ankles, shortness of breath, and so forth. A user can answer the questions using, for example, the touchscreen functionality of the user interface 104 and/or a keyboard and mouse of the user interface 104. In some implementations, the questions are provided in a scrolling window on the user interface 104, which can increase computational efficiency of the system 101, as a scrolling window is capable of reducing the need to load multiple individual pages.

An example list of questions that can be presented to a user through the user interface 104 include, but are not limited to, the following:

-   -   1. How old are you?     -   2. Has a doctor ever told you that you have diabetes or         pre-diabetes?         -   i. If yes, what was your A1C test result?             -   [I don't know]; [Below 5]; [Between 5-6]; [Between 6-7];                 [Above 7];     -   3. Approximately how often do you need to wake up in the night         to urinate?         -   [Rarely or Never]; [Sometimes]; [A few times a week]; [Once             every night]; [Many times every night];     -   4. Has a doctor ever told you that you have high blood pressure?         -   [No]; [Yes, 10 or more years ago]; [Yes, 5 or more years             ago]; [Yes, in the last few years, but less than 5];     -   5. Do you know of any blood relative(s) who have had kidney         disease (select all that apply)?         -   [Mother] [Father] [Brother/Sister] [Aunt/Uncle] [Cousin]             [None]     -   6. Please select each button that indicates how much each of the         sentences below applies to you:         -   i. I find that I need to urinate more often, especially at             night:         -   [Rarely]; [Often]; [Almost Always]         -   ii. I have more swelling of my feet and ankles than I             remember in the past: [Rarely]; [Often]; [Almost Always]         -   iii. I have dry/itchy skin: [Rarely]; [Often]; [Almost             Always]         -   iv. I have muscle cramps at night: [Rarely]; [Often];             [Almost Always]         -   v. I have trouble concentrating: [Rarely]; [Often]; [Almost             Always]         -   vi. I have trouble sleeping: [Rarely]; [Often]; [Almost             Always]         -   vii. I feel tired: [Rarely]; [Often]; [Almost Always]         -   viii. I feel cold even when others are not: [Rarely];             [Often]; [Almost Always]         -   ix. My urine is foamy or bubbly: [Rarely]; [Often]; [Almost             Always].

The weight sensor 105 is configured to capture weight data of a user. For example, the weight sensor 105 can be a digital weighing scale on which a user can stand or sit. When the user stands or sits on the weighing scale, the weighing scale can measure the weight of the user. For example, the force produced by the user's weight can cause a spring of the weighing scale to deform, and the amount of deformation can be measured by one or more transducers called strain gauges. A strain gauge is a conductor whose electrical resistance changes when its length changes.

The urinalysis sensor 106 is configured to capture urinalysis data of the user. For example, the urinalysis sensor 106 can include a slot configured to receive a vial of urine and a urine dipstick. A urine dipstick is a specially treated chemical strip having patches that, in response to being placed in the vial, changes colors to indicate the presence of abnormalities in the urine, such as excessive amounts of protein, blood, pus, bacteria, sugar, and white blood cells. In some implementations, the urinalysis sensor 106 includes actuators and other mechanisms that, once the urine vial is received, dips a pre-loaded dipstick into the urine vial. The urinalysis sensor 106 can also include optical equipment configured to detect the color changes on the patches of the dipstick.

The alert module 107 is configured to alert a user of a potential health issue. For example, the alert module 107 includes a printer, such as a toner-based printer, liquid inkjet printer, solid ink printer, and so forth. The alert module 107 provides a user with a read-out (i.e., a paper having representations of graphics and/or text) representing output from the computer processors 110, as will be described later in more detail. Additionally, or alternatively, the alert module 107 is integrated with the user interface 104. For example, the user interface 104 can display graphical representations and text representing output from the computer processors 110. Additionally, or alternatively, the alert module 107 can provide audible output for alerting the user of a potential health issue.

The bio-impedance sensor 108 is configured to capture and transmit hydration data of a user by determining a user's hydration status by measuring the impedance of a weak current flowing through the user's body due to body's water and electrolyte content. For example, the bio-impedance sensor 108 can include an electrode for sending a weak current through a user's body and can measure the amount of total body water in the user based on the measured impedance.

The computer processors 110 include a computer-readable medium 111. The computer-readable medium 111 includes computer-executable instructions 112. The computer-readable medium 111 (or computer-readable memory) can include any data storage technology type which is suitable to the local technical environment, including but not limited to semiconductor based memory devices, magnetic memory devices and systems, optical memory devices and systems, fixed memory, removable memory, disc memory, flash memory, dynamic random-access memory (DRAM), static random-access memory (SRAM), electronically erasable programmable read-only memory (EEPROM), and the like. In some implementations, the computer-readable medium 111 includes code-segment having executable instructions.

The computer processors 110 are communicatively coupled to the one or more acoustic sensors 120. In some implementations, the computer processors 110 include a general purpose processor. In some implementations, the computer processors 110 include a central processing unit (CPU). In some implementations, the computer processors 110 include at least one application specific integrated circuit (ASIC). The computer processors 110 can also include general purpose programmable microprocessors, special-purpose programmable microprocessors, digital signal processors (DSPs), programmable logic arrays (PLAs), field programmable gate arrays (FPGA), special purpose electronic circuits, etc., or a combination thereof. The computer processors 110 are configured to execute program code means such as the computer-executable instructions 112.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 carry out one or more operations. When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive health data of a user.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive, from the retina scanner 102, retinal data of a user. For example, as previously indicated, the retinal scanner 102 can capture high-resolution images of a user's retina. The computer processors 110 are configured to receive retinal data representing these images and extract certain biomarkers presented by the images that may indicate the presence of certain diseases such as CKD, diabetes, and so forth. For example, in some implementations, the computer processors 110 are capable of measuring, based on the received retinal image data, the volume of the retina, total thickness of the retina, and/or central subfield mean retinal thickness. These measurements can specify the presence of retinopathy (i.e., retinal disease) by indicating the presence of characteristic lesions of the retina, such as microaneurysms, hemorrhages, cotton wool spots, intraretinal microvascular abnormalities, hard exudates, venous beading, and so forth. The presence of these characteristic lesions may indicate that the user is at risk of having, for example, diabetes and/or chronic kidney disease.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive, from the blood pressure sensor 103, blood pressure data of a user. As indicated previously, the blood pressure sensor 103 can measure the systolic and/or diastolic blood pressure of a user. The blood pressure sensor 103 is capable of transmitting blood pressure data representing values in accordance with these measurements to the computer processors 110. High blood pressure may indicate that user is at risk of having or developing certain diseases, such as chronic kidney disease and diabetes. In some instances, high blood pressure is defined as systolic blood pressure measurement over 130 and a diastolic blood pressure measurement over 80. As indicated earlier, the blood pressure data can also (or alternatively) include pulse measurements, cardiac output measurements, vascular resistance measurements, oxygen saturation measurements, and so forth.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive, from the user interface 104, lifestyle data of the user. For example, as indicated previously, the user interface 104 can receive, from a user, answers to questions related to the user's age, height, race, ethnicity, tobacco usage, family history of kidney disease/diabetes, alcohol usage, diabetic history, and whether the user has been experiencing nausea, vomiting, loss of appetite, fatigue, sleep problems, changes in urination frequency, decreased mental sharpness, muscle cramps, persistent itching, chest pain, swelling of feed or ankles, shortness of breath, and so forth. The user interface 104 is capable of transmitting lifestyle data indicating answers to these questions to the computer processors 110. The answers to these questions may indicate a risk of the user having certain diseases. For example, older age, frequent tobacco use, and incidences of nausea may indicate that a user is at risk of having or developing chronic kidney disease or diabetes.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive, from the weight sensor 105, weight data of a user. For example, as indicated previously, the weight sensor 105 can measure the weight of a user. The weight sensor 105 is capable of transmitting weight data indicating the measured weight of a user to the computer processors 110. A user's weight may indicate that the user is at risk of having or developing chronic kidney disease and/or diabetes. For example, the computer processors 110 can determine a body mass index (BMI) of a user by using the user's measured weight and height measurements (e.g., as indicated by the user's answers received from the user interface 104 to questions related to the user's height). A high BMI (e.g., BMI value of 25 or greater) may indicate that a user is at risk of developing CKD or diabetes.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive, from the urinalysis sensor 106, urinalysis data of a user. For example, as indicated previously, the urinalysis sensor 106 can detect color changes on a dipstick used in a urine dipstick test that can indicate the presence of abnormalities in the urine (e.g., excessive amounts of protein, blood, pus, bacteria, sugar, white blood cells, etc.). The urinalysis sensor 106 is capable of transmitting urinalysis data representing the color changes corresponding to the dipstick to the computer processors 110. The presence of abnormalities in the urine may indicate that a user is at risk of having or developing CKD or diabetes. For example, the presence of certain proteins in urine, such as albumin, may indicate early signs of CKD. As another example, the presence of excess sugar (e.g., greater than 0.8 millimoles/liter) may indicate that a user is at risk of having or developing CKD or diabetes.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to receive, from the bio-impedance sensor 108, hydration data of the user. As indicated above, the hydration data can reflect a measurement of the amount of total body water in the user based on the measured impedance.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to detect, based on the received health data of a user, a potential health issue of the user (e.g., whether the user is at risk of having or developing CKD and/or diabetes). For example, if the received data indicates a high BMI, presence of albumin in the urine, frequent tobacco usage, and a family history of kidney disease, the computer processors 110 can determine that the corresponding user is at risk of having or developing CKD. In some implementations, the received data is assigned values. For example, a value can be assigned to the measured BMI (e.g., a “1” for a BMI of 18 or lower, a “2” for a BMI of 18-24, a “3” for a BMI of 25-29, and a “4” for a BMI of over 30). As another example, a value can be assigned to the answers to each question (e.g., a “1” for a yes answer and a “0 for a no answer). In some implementations, the computer processors 110 combine (e.g., sum, average, determine median, etc.) the assigned values to generate a health risk value and compare the health risk value to a threshold health risk value. If the health risk value exceeds the threshold health risk value, the computer processors 110 determine that the user is at risk of having or developing a potential health issue (e.g., CKD, diabetes, etc.). In some implementations, the computer processors 110 weight the assigned values. The weighting of the assigned values can be based on, for example, the predictive power of the underlying data for predicting whether or not a user is at risk of having or developing a potential health issue. For example, the presence of albumin in urine may be more predictive as to whether a user is at risk of having or developing CKD than a high BMI. Therefore, the values corresponding to the presence of albumin in urine can be weighted heavier than the values corresponding to a high BMI. In some implementations, the weighting scheme weights certain measurements in accordance with the following ranking (from highest to lowest):

1. Blood Pressure/Pulse measurement;

2. Hydration Status;

3. Retinal scan analysis;

4. Cardiac rhythm;

5. Cardiac output;

6. Peripheral vascular resistance;

7. Oxygen saturation.

When the computer processors 110 execute the computer-executable instructions 112, the computer processors 110 are configured to cause the alert module 107 to alert a user of a potential health issue in response to detecting the potential health issue of the user. For example, if the computer processors 110 detect that a user is at risk of having or developing CKD, the computer processors 110 can cause the alert module 107 to generate a print-out stating: “Based on the received input, it has been determined that you are at risk of having or developing chronic kidney disease. Please present this print-out to a health care provider for further information.” In some implementations, the print-out also lists the risk factors that lead to the determination (e.g., high BMI, albumin in urine, frequent smoking, etc.). As indicated earlier, this alert can be alternatively (or additionally) be provided by the user interface 104. In some implementations, the computer processors 110 can utilize a database (e.g., local, cloud-based, etc.) to help the user locate a healthcare professional that specialize in the detected potential health issue. For example, if the detected potential health issue is that the user is a risk of having CKD, the computer processors can utilize the database to identify one or more nephrologist that are local to the user's place of residency (e.g., within 60 miles of the user's place of residency). For determining the user's place of residency, the user interface 104 can prompt the user to provide, for example, their home address.

While the system 101 has been described as having a retinal scanner 102, a blood pressure sensor 103, a user interface 104, a weight sensor 105, a urinalysis sensor 106, and a bio-impedance sensor 108, the system 101 can have more or less of these components. For example, in some implementations, the system 101 can include two retinal scanners 102. In some implementations, the system 101 does not include a user interface 104, the urinalysis sensor 106, and/or the weight sensor 104. In some implementations, the system 101 does not include the retinal scanner 102. Consequently, the computer processors 110 can be configured to detect potential health issues based on the data available in accordance with the configuration of sensors/scanners of the system 101.

FIG. 3 shows a flowchart depicting an example of a method 300 for detecting potential health issues, in accordance with one or more embodiments of the present disclosure. For illustrative purposes, the method 300 is described as being performed by the system 101 for detecting potential health issues described previously with reference to FIG. 2. The method 300 includes receiving health data of a user (block 310), detecting a potential health issue of the user (block 320), and causing an alert module to alert the user of the potential health issue (block 330).

At block 310, the computer processors 110 receive health data of a user. For example, as previously indicated with reference to FIG. 2, the computer processors 110 can receive: retinal data from the retina scanner 102, blood pressure data from the blood pressure sensor 103, lifestyle data from the user interface 104, weight data from the weight sensor 105, and/or urinalysis data from the urinalysis sensor 106.

At block 320, the computer processors 110 detect, based on the received health data of the user, a potential health issue of the user (e.g., whether the user is at risk of having or developing CKD and/or diabetes). For example, if the received data indicates a high BMI, presence of albumin in the urine, frequent tobacco usage, and a family history of kidney disease, the computer processors 110 can determine that the corresponding user is at risk of having or developing CKD. In some implementations, the received data is assigned values. For example, a value can be assigned to the measured BMI (e.g., a “1” for a BMI of 18 or lower, a “2” for a BMI of 18-24, a “3” for a BMI of 25-29, and a “4” for a BMI of over 30). As another example, a value can be assigned to the answers to each question (e.g., a “1” for a yes answer and a “0 for a no answer). In some implementations, the computer processors 110 combine (e.g., sum, average, determine median, etc.) the assigned values to generate a health risk value and compare the health risk value to a threshold health risk value. If the health risk value exceeds the threshold health risk value, the computer processors 110 determine that the user is at risk of having or developing a potential health issue (e.g., CKD, diabetes, etc.). In some implementations, the computer processors 110 weight the assigned values. The weighting of the assigned values can be based on, for example, the predictive power of the underlying data for predicting whether or not a user is at risk of having or developing a potential health issue. For example, the presence of albumin in urine may be more predictive as to whether a user is at risk of having or developing CKD than a high BMI. Therefore, the values corresponding to the presence of albumin in urine can be weighted heavier than the values corresponding to a high BMI.

At block 330, the computer processors 110 cause the alert module 107 to alert the user of a potential health issue in response to detecting the potential health issue of the user. For example, if the computer processors 110 detect that the user is at risk of having or developing CKD, the computer processors 110 can cause the alert module 107 to generate a print-out stating: “Based on the received input, it has been determined that you are at risk of having or developing chronic kidney disease. Please present this print-out to a health care provider for further information.” In some implementations, the print-out also lists the risk factors that lead to the determination (e.g., high BMI, albumin in urine, frequent smoking, etc.). As indicated earlier, this alert can be alternatively (or additionally) be provided by the user interface 104. In some implementations, the computer processors 110 can utilize a database (e.g., local, cloud-based, etc.) to help the user locate a healthcare professional that specialize in the detected potential health issue. For example, if the detected potential health issue is that the user is a risk of having CKD, the computer processors can utilize the database to identify one or more nephrologist that are local to the user's place of residency (e.g., within 60 miles of the user's place of residency). For determining the user's place of residency, the user interface 104 can prompt the user to provide, for example, their home address.

Types of display devices can include, for example, a cathode ray tube (CRT), a liquid crystal display (LCD), a light-emitting diode (LED), and a plasma monitor. Display devices can include a keyboard and pointing devices including, for example, a mouse, a trackball, or a trackpad. User input can also be provided to the computer through the use of a touchscreen, such as a tablet computer surface with pressure sensitivity or a multi-touch screen using capacitive or electric sensing. Other kinds of devices can be used to provide for interaction with a user, including to receive user feedback including, for example, sensory feedback including visual feedback, auditory feedback, or tactile feedback. Input from the user can be received in the form of acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to, and receiving documents from, a device that is used by the user. For example, the computer can send web pages to a web browser on a user's client device in response to requests received from the web browser.

The term “graphical user interface,” or “GUI,” can be used in the singular or the plural to describe one or more graphical user interfaces and each of the displays of a particular graphical user interface. Therefore, a GUI can represent any graphical user interface, including, but not limited to, a web browser, a touch screen, or a command line interface (CLI) that processes information and efficiently presents the information results to the user. In general, a GUI can include a plurality of user interface (UI) elements, some or all associated with a web browser, such as interactive fields, pull-down lists, and buttons. These and other UI elements can be related to or represent the functions of the web browser.

The network can communicate with, for example, Internet Protocol (IP) packets, frame relay frames, asynchronous transfer mode (ATM) cells, voice, video, data, or a combination of communication types between network addresses.

The computing system can include clients and servers. A client and server can generally be remote from each other and can typically interact through a communication network. The relationship of client and server can arise by virtue of computer programs running on the respective computers and having a client-server relationship.

Cluster file systems can be any file system type accessible from multiple servers for read and update. Locking or consistency tracking may not be necessary since the locking of exchange file system can be done at application layer. Furthermore, Unicode data files can be different from non-Unicode data files.

While this specification contains many specific implementation details, these should not be construed as limitations on the scope of what may be claimed, but rather as descriptions of features that may be specific to particular implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented, in combination, in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations, separately, or in any suitable sub-combination. Moreover, although previously described features may be described as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can, in some cases, be excised from the combination, and the claimed combination may be directed to a sub-combination or variation of a sub-combination.

Particular implementations of the subject matter have been described. Other implementations, alterations, and permutations of the described implementations are within the scope of the following claims as will be apparent to those skilled in the art. While operations are depicted in the drawings or claims in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed (some operations may be considered optional), to achieve desirable results. In certain circumstances, multitasking or parallel processing (or a combination of multitasking and parallel processing) may be advantageous and performed as deemed appropriate.

Moreover, the separation or integration of various system modules and components in the previously described implementations should not be understood as requiring such separation or integration in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.

Accordingly, the previously described example implementations do not define or constrain the present disclosure. Other changes, substitutions, and alterations are also possible without departing from the spirit and scope of the present disclosure.

Furthermore, any claimed implementation is considered to be applicable to at least a computer-implemented method; a non-transitory, computer-readable medium storing computer-readable instructions to perform the computer-implemented method; and a computer system comprising a computer memory interoperably coupled with a hardware processor configured to perform the computer-implemented method or the instructions stored on the non-transitory, computer-readable medium.
